The Schedule referred to in these LettersPatent and making part of thesame To all wlwm 'it ma/y concern.-

Be it known that LMUNSON SIGLER, of Paterson, in the county of Passaic,and State of New Jersey, have inventeda new and improvedMethod ofRegulating the Warp-Tension in Weaving-Looms; and I do hereby declarethe following to bea full, clear, and exact description of the same,reference being had to the annexed drawing, making part of thisspecification, in which- Figure 1 is a side elevation, and

Figure 2, a rear elevation of a loom, with my improvement appliedthereto. l

The object of this invention is to maintain, automatically, a uniformtension uponthe warp of the moving fabric, as it rises and falls, in thefabrication of the cloth.

This object I accomplish by the use of a series of rollers, fitted in aswinging frame, and applied `to the loom so as to receive and hang inthe warp with such a degree of weight as may b e best adapted to thefabric to be'woven, 4said swinging frame being provided with anadjustment by which the weight upon the warp may be increased ordiminished, at the pleasure of the operator.

In the drawing- Y A represents the frame ofthe loom, and E represents apair of cams, by which the upward v and downward motion of the warp isobtained through the agency of levers, upon which said cams act,substantially in the manner shown, said levers being attached to thewaipby means of rigging-cords, as shown.

The swinging in the drawing by B. j

It consists pf two stands or brackets, which, in the v-drawing, aremarked B, and the upper ends whereof are united by means of aconnecting-rod reaching across the rear part ofthe loom, from onebracket to the other.

These brackets are provided with suitable bearings, to carry thejournals on the ends ofthe rollers,- of which there are three, arrangedsubstantially as shown, and each of said brackets is made with a slottedfoot, projecting inward,A the slot in the foot of said brackets beingmade to receive the studs Fupon which said swinging frame is supported,about which it swings or vibrates, and on which it is adjustedhorizontally, to regulate the weight or Atensile strain on the warp.

The vibrating brackets. or stands B, in thedrawing, are fitted -withthree rollers. The work, however, might be done with two, though not sowell, without a diier- Vent construction of stand or bracket.

ame above referred to is-represented` The journals of the top or thirdroller do not4 have their bearings in the brackets. The rollersimplylieson and between the two lower rollers, and is kept in position by meansof a pair of hook-journals, C, which reach down and hook on one of therods uniting the brackets, and which are tted with nuts at their tops,under which there are springs; made of any suitable material, and in'anysuitable form, by which means this top roller can be adjusted to thebottom rollers, as closely as may be desired, to keep the warp in itsplace, while, at the same time, Ait can -yield to any littleinequalityin the thickness ofthe warp, thus leaving the tension alwaysthe same, or as nearly so as can be desired in practice.

It has already beenl stated that the brackets B vibrate upon the studs Fupon whichthey are supported, .l

and itwill be seen that the further they pull back, the greater willbe-the tension upon the warp, and that, if there were nothing toregulate or limit the vibration, the wh'ole swinging frame might fallaway forward or away back, entirely destroying its utility. It istherefore necessary to have some means of regulating its vibrations,that is, of ixingvthe points between which it shall vibrate.

This I accomplish by means of a notched bracket, D, which fits in and isbolted on corresponding notches in the top of the frame-post A, andwhich is'made to project over the inside of the said post and embracethe4 stan'ds or brackets B, in a slot or recess in-which said standsvibrate, the hole through which the screw passes, to secure saidbrackets D to the frame, being made oblong, by which said brackets canbe moved back or forth, to increase or diminish the tension, as the casemay'require.

Having now described thenature and extentof my vin vention,

I claim as new herein, and desire to 4secure by Letters Patent- Thetension-regulator, consisting of a frame, made and fitted with rollersand applied to the loom, and governedin its operation, all substantiallyas described, for the purpose of securing a uniform tension of the warp,as set forth.

MUNSON .SIGLER.
